The 1930s saw the first commercial kitchen extraction created to keep kitchen air cleaner. They have continued to evolve over the last eighty years and are an integral part of every kitchen in many countries. The fan keeps the air clean and grease free in the area where regular cooking takes place. The more powerful and versatile fans of the twenty first century are a great improvement over their early counterparts.

The steam from cooking can make furniture and walls become moisture laden. When mold develops the doors might become deformed and open and close with difficulty. The wallpaper risks peeling and the wooden joints too might open. The kitchens of yesteryear were often finished in ceramic tile and separate from the rest of the house. The upper middle class usually had a hired cook and housekeeper to keep the kitchen surfaces clean and odor free.

Without extraction canopies strong cooking smells will pervade the house. The cooking oils vaporize and become trapped in room furnishings. This includes window coverings such as blinds or curtains as well as upholstered furniture and electronic equipment such as computers and tv monitors. The air needs to be changed ideally at twelve times per hour to keep the air free of airborne contaminants.

The fan extractor consists of three main sections starting with the familiar bell shaped hood. This helps to catch the rising gases coming from cooking foods. The shape has undergone some design changes so that a more contemporary flat, curved surface is familiar in many kitchens. The grease filter and fan motor make up the remaining two parts.

The shape such as the canopy will help to extract the odor-filled air replacing it with clean, odor free air. The old air is ducted outdoors but when lack of space prevents the installation of ductwork then a charcoal filter is used for catching odors. Regular washing will ensure it reaches its longevity of three years. Teh second aluminum filter will capture grease and should also be washed regularly.

The width of the canopy comes in sixty or eighty centimeters to match the width of the stove. The ceiling mounted hoods must be attached to reinforced ceilings. The popular island integrated stove is accompanied by a canopied fan above it. This is controlled by remote and is a more expensive but powerful fan too. It will contain halogen or fluorescent lighting to light the food preparation area on the stove top.

The standard canopy is available in several colors as well as stainless steel. The aluminum grease filter as well as charcoal filters work together to prevent grease from spreading in the room. The filters will need to be washed every three to four months depending on the frequency of use.

The installation of the extractor fan is ideal when the ducting route is short and direct. The round, rigid shape of the duct is the fastest for extracting the contaminated air. The second choice for ductwork is the rectangular shaped system. The ductwork is usually hidden in the ceiling but industrial kitchens often have them exposed since there is no need to hide the system.The accessibility to cleaning the ducts is also easier when it is not covered up.

If you have a large kitchen, your commercial kitchen extraction will be a necessary installation. Go to Extraction Canopies for brilliant deals on extraction canopies
